Storage of Jopen 5.5 and 6.5

You have to be careful to separate silicone toys when storing them because if they are left touching then they can start to fuse, right? So, when you're storing vibes with multiple long and flexible arms, like the Jopen Vanity 5.5 or 6.5, do you need to put something between the arms? I'm curious about the 5.5 in particular, but that's an awful lot of money for a vibe that ends up fused to itself. Did Jopen/Cal Exotics update the material somehow to avoid this problem?
